Abstract

resumo patente de invenção: "dispositivo de controle de quantidade de injeção de combustível". a presente invenção refere-se a um sistema de quantidade de injeção de combustível equipado com um aquecedor de combustível em que, dependendo de se o aquecedor está em operação (etapa s1), uma ecu de efi determina um valor inicial de um valor de correção ekthwst para corrigir uma quantidade de correção de injeção com referência a um mapa de valor inicial sem aquecimento (etapa s2) ou determina o valor inicial do valor de correção ekthwst para corrigir a quantidade de correção de injeção com referência a um mapa de valor inicial de aquecimento se o aquecedor estiver em operação (etapa s3). deve-se observar, no presente documento, que o valor inicial do valor de correção ekthwst é definido mais baixo sob a mesma condição no mapa de valor inicial de aquecimento que no mapa de valor inicial sem aquecimento.patent summary: "fuel injection quantity control device". The present invention relates to a fuel injection quantity system equipped with a fuel heater wherein, depending on whether the heater is in operation (step s1), an efi ecu determines an initial value of a correction value. ekthwst to correct an injection offset amount with reference to an unheated start value map (step s2) or determine the initial value of the injection value ekthwst to correct the injection offset amount with reference to an unheated start value map heating if the heater is in operation (step s3). It should be noted here that the initial value of the correction value ekthwst is set lower under the same condition in the initial heating value map as in the unheated initial value map.
